UK-POLOS.NET - THE VW Polo Forum

Just as i was telling the owner of a rather disgusting corsa that ive never had any problems with my polo ( well no major ones) my polo has started overheating the radiatir fan is not kicking in has anyone come accross this problem before?????? Help as i would love to take her to her first meet in monday

Either

1 - your thermostat isnt working

or

2 - your radiator switch has had it

or

3 - the radiator fan fuse has failed.

Mine overheated the other week....ended up being the thermostat so I took it out!

@Bobby - I hope you have bought a new thermostat and refitted it?

I've bought a new one, not fitted it yet though!....a job for Monday methinks.

Thanks for the help guys bought thermo and rad switch coming tomoro had to botch the fan with a switch till tomoro

Does anyone have the part number for the radiator switch as the one everyone is giving me seems to be different i keep getting a rectangular switch with three prongs and the switch for mine seems to be a black (not grey) square switch with three prongs. Help please does anyone have a pic of the location am i looking i the wrong place

What year is your GTI?

Rad switch is located to the the right of the radiator if you are looking down onto it

2000 mate had the switch and thermo changed but fan still not kicking in any ideas????

How hot is it getting?

I'm going with blocked rad, airlock or failed waterpump

Have you checked the fan fuse?

the fuse is fine so ive decided tomoro going to buy new water pump new fuse for it and pray to god it works as im spending
money on maintenance instead of cosmetics lol thanks for the help alex

If your doing the pump, flush the system out - disconnect the two rad hoses, and stick a hose pipe in the top and see how easily water flows out the bottom.

Just out of interest Alex, what are the consequences of running the car without a thermostat?

No I haven;t put the new one in yet!

Overcooling mainly. The water is always circulating through the rad, so it takes a long time to heat up, and wont stay hot as when you move off, itll be instantly cooled again

Can do damage, plus will drop your economy

Fit it asap

Thanks mate, will do. Any advice on the sealant to use when I put the housing back on again?
